Japanese astronomers believe they have discovered a black hole in the center of the Milky Way which weighs 100,000 times as much as our sun.
That in the center of our galaxy, most likely a black find hole is several million times weigh as much as our sun, is already known for a while. But the Japanese astronomer Tomuharu Oka and colleagues think now have a second black hole found in the same area . And that would have a mass of about 100 000 times that of the sun.
Most logical explanation
The latter is quite remarkable, because black holes come as far as we know two types First, there is the type of black hole that’s left over when a massive star exploded,. weighing up to several tens of times as much as our sun Secondly, there are the supermassive black holes millions. to billions of times as many roads as our sun. The hole of Oka and his team would fall into neither category, but the first example of a so-called his intermediate-mass black hole .
The astronomers came to the hole on the track through a gas cloud which she had found previously subject to an investigation. This showed that the gas in the cloud had a variety of different speeds. A computer then showed that an object with 100,000 times the mass of our sun, condensed into an area with a diameter of 0.3 light years, could be responsible. And since in the affected area is nothing to see, a black hole seems to be the most logical explanation.
Not the first time
Moreover, it is not the first time that astronomers have invented a intermediate-mass black hole found at; in 2004, 2006, 2009 and 2012, however, happened already. None of these claims is now seen as an unambiguous discovery. The question now is whether the ‘Japanese’ black hole a while indeed accepted by the scientific community. Otherwise, this find only the above-mentioned list of maybes again become slightly longer
